滩坝砂地震精细解释软件开发及实现

摘要

As the beach bar sandstone reservoir has large depth,thin thickness for a single reservoir (sand dam is mostly a few meters thick and beach sand under 2 m),lager lateral change and weak seismic reflection,the conventional software can hardly fine interpret and predict the reservoir due to these restrictions.Based on studying the beach bar sandstone fine interpre-tation methods,the author uses C# language which based on.NET's Visual Studio 2010 platform to develop the software which used for beach bar sandstone fine interpretation (Seis_BBS,Beach Bar Sandstone).The software has the following char-acteristics:1)the software integrates beach bar sandstone feature analysis,forwarding modeling,target processing and fine de-scription.2)the software includes many new methods and new technologies to analyze the beach bar sandstone reservoir,such as the three parameter wavelet thin interbed detection method,the fusion display of ancient landform and seismic attribute method,multi-wavelet to eliminate the strong shielding effect method,the HHT method,which make up the disadvantages of commercial software in these aspects.3)the software which developed by C# has good portability and scalability,you can add new interpretation methods to the software in the following study easily.%滩坝砂储层埋藏深，单个储层较薄（坝砂大多几米厚，而滩砂多在2m以下），横向变化大，地震反射弱，很难用常规软件进行精细描述与预测。这里在研究滩坝砂精细解释方法基础上，使用C＃语言，在基于．NET的Visual Studio2010平台上，开发出一套用于滩坝砂精细解释的软件（Seis_BBS：Beach-Bar Sandstone）。Seis_BBS 具有以下特点：①软件集滩坝砂特征分析、正演模拟、目标处理、精细描述于一体，具有很强的实用性；②软件中采用了三参数小波薄互层检测、古地貌与地震属性融合、多子波消除强屏蔽效应、基于 HHT 的目标处理等多项滩坝砂解释新方法、新技术，弥补了商业软件在这方面的不足；③模块由C＃语言开发，具有很好的移植性，可扩展性高，可以随时将后续新的解释方法添加到软件中。
